SPECIFICATION forming part of Letters Patent No. 667,876, dated February 12, 1901. Application led May 14, 1900. Serial No. 16,584. (No model.)

To (all whom it may concer-rt:

Be it known that I, PETER HABEGER, a citizen of the United States, residing at West Bend, in the county of Palo Alto and State of Iowa, have invented a new and useful Improvement in Grain 'lhreshers and Separators, of which the following is a specification.

My Objectis to provide means for more thoroughly shaking and separating straw and To grain as they are passed rearward from the cylinder in a threshing-machine.

Heretofore cross-bars have been fixed to the side bars of a straw-shaker and tines fixed to the cross-bars. Auxiliary frames have also been xed to the side bars of a straw-shaker to project upward and rearward and rakes pivotally connected with the free ends of the auxiliary frames; but in no instance have shaker-frames been provided with iixed tines zo and arranged and combined in a shaker and with curtains, as contemplated by my invention, which consists in the arrangement and combination of a plurality of auxiliary shakers or forks with a vibrating straw shaker and carrier, ashereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in Which- Figure l is a longitudinal sectional View of a portion of a thresher, a straw carrier and 3o shaker, and my auxiliary shakers or forks combined therewith, as required for practical use. Fig. 2 is a top view of the improved straw shaker and carrier shown in Fig. l.

The letter A designates a portion of the frame and top, and A2 the side wall, of a threshing-machine.

B represents a threshing-cylinder, and B2 a beater mounted in the front end portion of the machine-frame.

4o C and C2 are the parallel side bars of the frame of a shaker mounted upon supports D and D2, that are pivotally connected with the side walls of -a machine in such a manner that when vibrated they will impart reciprocating .4.5 longitudinal motions to the shaker and the auxiliary shakers or forks combined therewith and carried thereby. Cross-pieces f, xed on the top surfaces of the side pieces of the main shaker-frame, have inclined top 5o faces, as shown in Eig. 1.

At intervals alongl the length of the carrierframe round bars or fork-tines h are fixed to cross-pieces gto extend rearward and upward from their rear faces in such a manner that straw will be elevated thereby and shaken thereon to facilitate the separation of grain from the straw.

Auxiliary frames and straw-shakers com posed of parallel side pieces J and J2 and cross-pieces f are iixed to the side bars of the 6o main shaker-frame to extend upward and rearward therefrom, and a plurality of crosspieces g, having fixed projections or tines 7L, extending upward and rearward, are also fixed to said auxiliary frames, as shown in Fig. 1, in such a manner that straw will be elevated thereby and shaken as it passes rearward from the cylinderand beater at the front end of the machine.

K and K2 are iiexible deiiectors suspended 7o over the straw shaker and carrier to prevent straw from being forced over the front portion of the shaker and carrier Without being subjected `to its shaking and separating action.

It is obvious that when straw is elevated by means of the auxiliary shakers it will at the same time be shaken and separated to facilitate dropping of the grain from the straw and that the straw also will drop from the 8o ends of the fork tines or projections h of the auxiliary shakers and in doing so aid in separating the grain from the straw during the passage of the straw and grain rearward from the cylinder.

Having thus described the construction and operation of my invention, its practical utility will be understood by persons familiar with the art to which it pertains.

What I therefore claim as new, and desire 9o to secure by Letters Pat-ent therefor, is*- 1. In a thresher and separator, a strawshaker comprising side bars, a plurality of cross-pieces fixed thereto, tines fixed to said crosspieces to project rearward, auxiliary frames, composed of side pieces and crosspieces, xed to the side bars of the strawshaker and tines fixed to the cross-pieces of the auxiliary frames, arranged and combined as shown and described to operate in the man- 10o ner set forth for the purposes stated.

2. ln a thresher and separator, a strawshaker comprising. side bars, a plurality of der and over the front end portion of the cross-pieces fixed thereto, Lines Xed to said straw shaker, arranged and combined as xo cross-pieces to project rearward, auxiliary shown and described to operatein the manframes composed of side pieces and crossner set forth for the purposes stated.

5 pieces 'fixed to the side bars of the straw- PETER HABEGER. shaker and laines xed to the cross-pieces of Witnesses. the auxiliary frames, and curtains iixed to W. B. LANG, the roof of the machine in rear of the cylin- W. K. SWEENY.
